1Lookup vs ZeroBounce

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

1Lookup

$99/mo 7 day free trial

One API for checking phone numbers, emails and IP addresses before they reach your dialer, sequencer or ATS, with contact enrichment and B2B data on the same credits. Plans start at $99/mo for 20,000 checks with a 7-day free trial, so it suits teams verifying in volume rather than a few lists a month.

Where 1Lookup fits

  • Agencies running texting or calling campaigns that need to scrub numbers for line type and DNC
  • Teams verifying emails and phones in bulk before loading them into an ATS or sequencer
  • Developers who want validation and enrichment behind one API key
  • Claude users who want to verify contacts from a chat

ZeroBounce

$39/2,000 credits Free tier

Email validation and scoring. Free 100 credits; ZeroBounce ONE starts at $99/mo for 10,000 validations.

Where ZeroBounce fits

  • Recruiting and sales teams cleaning lists before send
  • Ops that want validation as an API
  • Desks that need scoring, not only deliverable/undeliverable
  • Buyers who want a no-commitment free 100 credits

Where they pull apart

1Lookup

Stands out: Phone checks are the strength: line type, carrier and DNC status come from FCC and carrier data refreshed daily, so recruiters can drop landlines and do-not-call numbers before a texting or calling campaign. Email, IP and enrichment lookups share the same balance, unused credits roll over for 3 months, and an MCP server lets Claude run checks directly.

Watch out: There is no free plan or pay-as-you-go pack; the cheapest option is a $99/mo subscription, which is a lot if you only verify a few hundred emails. Enrichment gets expensive fast at 10 to 75 credits a lookup. It is an API and dashboard product with no recruiting workflow, and the MCP server covers only validation, not enrichment.

Not the right fit for

  • Recruiters verifying a few hundred emails a month (a pay-per-credit verifier costs less)
  • Buyers who want a free plan
  • Teams looking for a sourcing database or outreach tool

ZeroBounce

Stands out: Validation plus quality scoring on one meter, with a real free 100-credit allowance and a public $99/month subscription.

Watch out: Pay-as-you-go starts at $39 for 2,000 validations if you do not want a subscription. Heavy lists will burn the 10,000-credit ONE cap.

Not the right fit for

  • Teams that needed a finder, not a verifier
  • High-volume senders who will outgrow 10k/month immediately

Pros and cons

1Lookup

  • Daily FCC and carrier data for phone line type and DNC
  • Validation and enrichment share one credit balance
  • First-party MCP server with OAuth sign-in
  • No free plan; starts at $99/mo
  • Enrichment lookups cost 10 to 75 credits each
  • MCP server covers validation only

ZeroBounce

  • Public $99/mo ONE plan for 10k validations
  • 100 free credits, no trial needed
  • API plus MCP
  • ONE's 10k cap is easy to blow on a big agency list
  • Does not find emails, only validates them
  • Pay-as-you-go $39 pack is easy to miss if you only look at $99
